Abstract

Description

Field of the Invention

The present invention relates to communication technologies and in particular to an apparatus and a method for routing message services.

Background of the Invention

The IP Multimedia Subsystem (IMS) is a core subsystem in a Next Generation Network (NGN). With the packet domain as the bearer of its upper layer control signaling and media transport, with Session Initiation Protocol (SIP) as its service control protocol to make use of the simple implementation, easy scalability and convenient media combination of SIP, the IMS separates service control from bearer control and provides rich multimedia services.

Main functional entities in an IMS include a Call Session Control Function (CSCF) that controls user registration and sessions, an application server message service control unit that provides various service logic control functions, a Home Subscriber Server (HSS) that manages user subscription data in a centralized way, and a Media Gateway Control Function (MGCF) that interworks with circuit switched networks. A user accesses the network via a local P-CSCF of the visited location while session and service triggering control and service control interaction with the message service control unit are implemented by a home service node control unit in the registration location.

There are multiple types of message services provided in mobile and fixed networks. Some services are supported by both mobile and fixed networks, and some services are only supported by the mobile network or the fixed network. For example, text message services, like Short Message Service (SMS), are applied in mobile networks while instant message services are applied in fixed networks. Message services provided in a mobile network include text message service and Multimedia Message Service (MMS). Message services provided in a network include Instant Message (IM) and chat.

The following describes a technical solution in the prior art that implements text message service and MMS based on Internet Protocol (IP) with reference toFigures 1-3:

The 3rd Generation Partnership Project (3GPP) TS 23.804:Technical Specification Group Services and System Aspects; Support of SMS and MMS over generic 3GPP IP access defines an architecture for implementing IP-based text message service and MMS.Figure 1 shows anarchitecture 100 that implements text message service and MMS based on IP as defined in 3GPP TS 23.804.

In the network shown inFigure 1, the functions of main entities are as follows:

Short Message Service Center (SM-SC) 104, adapted to relay, store and forward short messages between a base station and a Short Message Entity (SME);

GMSC/SMS-IWMSC 108: MSC is a Mobile-services Switching Centre; SMS-GMSC is a Gateway MSC for Short Message Service; SMS-IWMSC is an Interworking MSC for Short Message Service;

IP-Message-GW 114: An IP Short Message Gateway that transfers short messages between a user equipment (UE) and the SM-SC.

The following describes a message flow in the network shown inFigure 1 with reference toFigure 2.

Figure 2 shows a message flow in the network shown inFigure 1. The message flow includes:

S202: A UE registers with the IP-Message-GW;

S204: The UE sends an SMS message to the IP-Message-GW;

S206: The IP-Message-GW transfers the SMS message to the SMS-IWMSC;

S208: The SMS-IWMSC transfers the SMS message to the SM-SC;

S210: The SM-SC sends a delivery report to the SMS-IWMSC;

S212: The SMS-IWMSC sends the delivery report to the IP-Message-GW;

S214: The IP-Message-GW sends the delivery report to the UE.

Figure 3 shows an MMS origination procedure in the network shown inFigure 1, including:

S302: Registration procedure;

S304-S308: A UE sends an MMS message to the IP-Messaging-GW;

S310: The IP-Messaging-GW sends the MMS message to the recipient UE;

S312-S314: A response message indicating successful delivery of the MMS message is received;

S316-S322: When the originating UE requests a delivery notification, a delivery notification is sent to the MMS originating UE via an SMS message; and

S324-S330: The delivery notification SMS is transmitted to the MMS originating UE.

When a UE accesses an network, it is needed to route the message to the IP-Message-GW. However, in the prior art, the technical solution proposed by 3GPP TS 23.804 does not solve the routing issue.

With reference toFigure 4, another technical solution in the prior art for implementing IP-based SMS and MMS is described in detail as follows.

The prior art also provides a routing method for message service and SMS interworking: UE originated message service information is routed to a Breakout Gateway Control Function (BGCF); the BGCF routes the message service information to the IP-SM-GW and finally the IP-SM-GW transfers the message service information to the SMS network of the message terminator.

Figure 4 shows a successful mobile originated (MO) message to SMS submit procedure in the network system according to the routing method for message service and SMS interworking in the prior art. The procedure includes:

S402: A UE is registered in the network successfully;

S404: The UE sends message service information to the S-CSCF;

S406: The S-CSCF checks the receiver identifier carried in the message service information and if the S-CSCF does not find a SIP Uniform Resource Identifier (SIP URI) associated with the receiver identifier, the S-CSCF routes the message service information to the BGCF;

S408: The BGCF selects to transmit the message service information to the IP-SM-GW according to a local policy;

S410: The IP-SM-GW performs service authentication; and

S412-S416: The IP-SM-GW forwards the message indicating that information is received to the UE.

Based on all the embodiments, the processing methods in the following scenarios can be deduced:

1) Multimedia message service information is sent to the home multimedia message service network of the message service information receiver;

2) Multimedia message service information is sent to the home text message service network of the message service information receiver;

3) Text message service information is sent to the home text message service network of the message service information receiver; and

4) Text message service information is sent to the home multimedia message service network of the message service information receiver.

When there is only in-session or out-session message service information in the entire network, the operations in the message service information transfer method judging module may be omitted. The message service information receiver home network judging module 520 directly delivers the message service information to the in-session message service information interworkinginterface module 550 or the out-session message service information interworkinginterface module 560.

The technical solution provided by embodiments of the invention judges that the home network of the message service information receiver is a traditional circuit switched network according to the message service information receiver identifier, judges that the message service information is carried via a session request message, and then transfers the message service information to the home short message network of the message service information receiver. With the technical solution, the network is able to route a message to the IP-Messaging-GW when a UE accesses. The technical solution also solves the interworking between non-session based message service and the multimedia message service as well as the interworking between session-based message service and the message service in a heterogeneous network such as the traditional circuited switched domain.

It should be understood that the above message service routing method is applicable to the message service interworking between the home network of the message service information transmitting module and a heterogeneous network. The heterogeneous network is a network that has an architecture different from that of the home network of the message service information transmitting module. For example, when the home network of the message service information transmitting module is an IMS network or another SIP network, a traditional circuit-switched network or a packet switched network is a heterogeneous network of the home network of the message service information transmitting module.

From the above description, it can be seen that the embodiments of the invention achieve the following technical benefits:

Although the technical scheme of the present invention has been described through exemplary embodiments, the invention is not limited to such embodiments. It is apparent that those skilled in the art can make various modifications and variations to the invention without departing from the scope of the invention. The invention is intended to cover the modifications and variations provided that they fall in the scope of protection defined by the claims.
